The Yamgraz were an indigenous people who used to live in Stain'd-by-the-Sea.
The Yamgraz people used to live on the shoreline of the area that would become Stain'd-by-the-Sea, where the Clusterous Forest later grew. They were mainly shellfishing people, and would harvest oysters to eat from the innards and use the shells as tools and castanets.
When fishing boats arrived, ink was discovered in the sea, and soon settlers ended up in the area. They built a railway that transported the oysters to the city for fancy parties, cutting off the food supply of the Yamgraz.
The people eventually disappeared, with the Yamgraz only being remembered in town by a street named after them.
- The book on the Yamgraz in Stain'd-by-the-Sea's Library is noted to have a cover design that looks like an unsightly oyster. Lemony Snicket notices Dashiell Qwerty bushing the spine after Nurse Dander's visit.
